CROSS-REFERENCE TO RELATED APPLICATION

This application is a National Phase entry of PCT Application No.PCT/CN2016/083638, filed on May 27, 2016, which claims the priority toChinese Patent Application No. 201610256377.2, titled “HAND-HOLD VACUUMCLEANER”, filed with the Chinese State Intellectual Property Office onApr. 22, 2016, which are incorporated herein by reference in its theirentireties.

FIELD

The present application relates to a hand-hold vacuum cleaner.

BACKGROUND

A vacuum cleaner, as a domestic appliance, is widely used for indoor andoutdoor cleaning. Current vacuum cleaners may be classified, accordingto shapes, into horizontal type, vertical type, hand-hold type, etc.Hand-hold type vacuum cleaners are usually powered by built-in batteriesto facilitate cleaning of cars or outdoor items, therefore more and moreChinese families begin to use hand-hold vacuum cleaners. In order toimprove dust removal efficiency, a hand-hold vacuum cleaner generallyincludes a machine body provided with a handle, a cyclone dust separatormounted in the machine body, a telescopic tube connected to the cyclonedust separator, a motor and a battery mounted in the machine body, andan air-out filter device. In the conventional technology, thesecomponents are generally laid out as disclosed in the Chinese patentCN101489454B, that is, the motor and the battery are respectivelyarranged at an upper end and a lower end of the handle, and the air-outfilter device is arranged at the rear of the motor. Since the air-outfilter device is restrained by the shape of the motor, it has a smallsectional area, poor filtering effect, and is required to be replacedfrequently. Moreover, since the airflow first flows through the motorand then is discharged to the outside through the air-out filter device,the air-out passage is not smooth and is relatively short, and the noisereduction effect thereof is not significant. Moreover, since the motoris far from the battery, the wiring thereof is complicated. Since thecenter of gravity of the conventional vacuum cleaner is at the frontpart in usage, it is laborious to use the vacuum cleaner. Besides, thehandle angle thereof does not conform to usage habits.
